SECTION 1: OUR RECOMMENDATIONS
This section describes our recommendations to help you in deciding which types of accessories to purchase for your new
Modeltech SE5a Scout ARF. Please read through this entire section very carefully. We have provided you with tips
and recommendations that, if followed, will result in a great flying airplane. Failure to follow our recommendations
may result in a poor flying airplane.
What Engine Should I Use?
The SE5a Scout ARF will fly well with a variety of different engines. The airplane is designed to be flown with .40 - .52 size
two-stroke engines or .52 - .61 size four-stroke engines. Whether you plan on using a two-stroke or a four-stroke engine,
the firewall has been set up for the engine to be mounted upright. This is ideal because the engine can be fully enclosed
within the cowling and engines that are mounted upright are very easy to tune and maintain.
If you choose to use a two-stroke engine, you will need to purchase a muffler extension for your engine's muffler. This will
allow the muffler to be pushed out far enough to clear the side of the fuselage. If you're using a four-stroke engine, the
engine's exhaust pipe can be rotated to exit the upper, right side of the cowling, so no muffler extension is necessary.
What Radio System and Servos Should I Use?
A standard four-channel radio control system with 3 standard servos for the elevator, rudder and throttle, and 2 mini servos
for the ailerons will be more than adequate. Since the ailerons use separate aileron servos, you will need to use a servo
Y-Harness to join them. A standard flat or square 4-cell receiver flight battery will work well, too.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦Because of the thin airfoil, you must use mini servos for the ailerons. Standard-size servos will not fit
within the confines of the wing.
What Else Do I Need?
The SE5a Scout ARF includes most of the hardware you'll need to finish the airplane. You will need to purchase separately
a remote fueling valve, two servo extension leads and one Y-Harness for the aileron servos, and some basic building
materials, such as adhesives, protective foam rubber for your radio equipment, and fuel tubing. We've provided a list
below of the items we used on the airplane shown in this instruction manual.
Here's a List of What We Used to Finish Our SE5a Scout ARF:
QTY. 1 210980 Magnum XL .52RFS Four-Stroke Engine
QTY. 1 608660 APC 12 x 6 Composite Propeller
QTY. 3 444104 Cirrus CS-36 Standard Servos
QTY. 2 444422 Cirrus CS-20HP Mini Servos

SECTION 4: REPLACEMENT PARTS
On the Web
http://globalservices.globalhobby.com
SECTION 5: A NOTE ABOUT COVERING
The covering material used on the Modeltech SE5a Scout ARF is real iron-on, heat-shrink covering material, not cheap
"shelf paper." Because of this, it is possible with heat and humidity changes that the covering on your airplane may
wrinkle or sag. This trait is inherent in all types of heat-shrink material. To remove any wrinkles that might be visible
you will need to purchase, or borrow from a fellow modeler, a heat iron. If you need to purchase one, the Global Heat
Sealing Iron # 360900 is recommended.
Follow this simple procedure to remove the wrinkles:
❑Plug in and turn on the sealing iron to the medium-high temperature setting. Allow the sealing iron to heat up for
approximately 5 - 7 minutes.
❑After the sealing iron has reached temperature, lightly apply the sealing iron to the wrinkled section of the covering.
Move the sealing iron slowly over the wrinkled section until the covering tightens and the wrinkles disappear.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦You will notice that the color of the covering will darken when it is heated. When the covering cools
back down, it will return to its normal color.
☞If the color layer smears from any of the seams the temperature of the sealing iron is too hot. Turn the temperature dial
down and wait about 5 minutes for the sealing iron to adjust to the lower temperature. You can remove any excess color
streaks using a paper towel soaked with a small quantity of Acetone.
We do not suggest storing your airplane in an extremely hot environment (like the back of your car in direct
sunlight) for any length of time. The extreme heat could cause the covering material to wrinkle or sag and possibly
damage the fragile components of the radio system.

YOU'LL NEED THE FOLLOWING PARTS FROM THE KIT:
YOU'LL NEED THE FOLLOWING TOOLS AND SUPPLIES:
SECTION 6: STABILIZER INSTALLATION
STEP 1: MOUNTING THE BOTTOM WING
❑Place the wing into the wing saddle, push it forward
completely, then push the trailing edge down into place and
line up the predrilled holes in the trailing edge with the predrilled
holes in the wing mounting block inside the fuselage.
☞A slot has been precut in the forward bulkhead to accept
the wing hold-down tab in the leading edge of the wing.
❑Remove the two ailerons and four C/A style hinges from the bottom wing and set them aside for now.
❑Using a modeling knife, cut away and remove the covering material from over the top and bottom of the two predrilled
holes in the trailing edge of the wing. The holes are located approximately 3/4" in front of the trailing edge and 1-1/4" out
from the centerline.
❑Using a modeling knife, cut away and remove the covering material from over the top of the two predrilled holes in the
plywood wing-screw doubler. Look carefully at the predrilled holes in the wing-screw doubler. You will notice that they are
not centered, but drilled more toward the back edge of the wing-screw doubler. When you install the wing-screw doubler in
the next procedure, the back edge of the wing-screw doubler should be even with the trailing edge of the wing.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦Do not glue the wing-screw doubler to the
wing. The wing-screw doubler must be able to be removed
when you remove the wing from the fuselage. This is
because the landing gear support strut will be mounted
permanently to the wing-screw doubler.
❑Secure the wing into place, using the wing-screw doubler,
two M4 x 30mm machine screws and two M4 flat washers.
☞Orientate the wing-screw doubler so that the back edge is
even with the trailing edge of the wing. The wing-screw
doubler should not overhang the trailing edge of the wing.

STEP 2: ALIGNING THE VERTICAL STABILIZER
❑Remove the rudder and three hinges from the vertical stabilizer and set them aside for now, then remove the elevator
and four hinges from the horizontal stabilizer and set them aside for now, too.
❑Using a modeling knife, cut away and remove the covering
material from over the bottom of the precut slot in the middle of
the horizontal stabilizer.
❑Push the vertical stabilizer into the mounting slot in the top
of the horizontal stabilizer. To align the vertical stabilizer
properly, the trailing edge of the vertical stabilizer should be
even with the trailing edge of the horizontal stabilizer and the
vertical stabilizer should be pushed down firmly.
❑Using a builder's triangle, check to make sure that the
vertical stabilizer is aligned 90º to the horizontal stabilizer.
❑While holding the vertical stabilizer firmly in place, use a
pencil to draw a line on each side of the vertical stabilizer where
it meets the top of the triangle stock on the horizontal stabilizer.
STEP 3: MOUNTING THE VERTICAL STABILIZER
❑Remove the vertical stabilizer and use a modeling knife to
carefully cut away and remove the covering material from
below the lines you drew.
✦✦
✦✦
✦WARNING✦✦
✦✦
✦When cutting through the covering to remove
it, cut with only enough pressure to cut through only the
covering itself. Cutting down into the balsa structure could
weaken the stabilizer and cause it to fail during flight.

❑Mix and apply a generous amount of 30 minute epoxy to the gluing surfaces of the vertical stabilizer and to the vertical
stabilizer mounting slot in the top of the horizontal stabilizer.
❑Push the vertical stabilizer down into place and realign it, double-checking the alignment once more before the epoxy
sets up. Remove any excess epoxy, using a paper towel and rubbing alcohol, and use pieces of masking tape to hold the
vertical stabilizer in place until the epoxy has fully cured.
☞Don't forget to double-check that the vertical stabilizer is perpendicular to the horizontal stabilizer.
STEP 4: ALIGNING THE HORIZONTAL STABILIZER ASSEMBLY
❑Using a modeling knife, cut away and remove the covering
material from the top of the stabilizer mounting platform.
❑Set the stabilizer assembly into place and temporarily align
it. The front of the vertical stabilizer should be centered over
the middle stringer in the top of the fuselage and the trailing
edge of the vertical stabilizer should be lined up with the sides
of the fuselage. The trailing edge of the horizontal stabilizer
should be even with the back edge of the fuselage, too.
❑Use a ruler to carefully measure the distance between the
tips of the horizontal stabilizer and the tips of the bottom wing.
Pivot the front of the stabilizer assembly (making sure that the
back of the stabilizer assembly stays centered) until both of
these measurements are equal. When both measurements
are equal, the stabilizer assembly is square to the wing.
❑When you are satisfied that the stabilizer assembly is square to the wing, use a pencil to draw a couple of marks on
each side of the front of the horizontal stabilizer where it and the fuselage sides meet, then use a couple of pieces of
masking tape and/or T-pins to hold the stabilizer assembly firmly in place and aligned.
❑When satisfied with the alignment, hold the stabilizer assembly in position, using a couple of T-Pins or masking tape.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦Before proceeding, it's important that the bottom wing be installed securely onto the fuselage. It must
be installed so that you can line up the stabilizer assembly properly.
Continued On Next Page
☛☛
☛☛
☛

11
❑With the stabilizer assembly held firmly in place, look from
the front of the airplane at both the wing and the horizontal
stabilizer. When aligned properly, the horizontal stabilizer
should be parallel to the wing.
STEP 5: MOUNTING THE HORIZONTAL STABILIZER ASSEMBLY
❑When satisfied with the fit and alignment, make sure that
the stabilizer assembly is secured firmly into place, and use a
pencil to draw a line on each side of the bottom of the
horizontal stabilizer where it meets the fuselage sides.
❑Remove the stabilizer assembly. Using a modeling knife,
carefully cut away and remove the covering material from
between the lines you drew.
✦✦
✦✦
✦WARNING✦✦
✦✦
✦When cutting through the covering to remove
it, cut with only enough pressure to cut through only the
covering itself. Cutting down into the balsa structure could
weaken the stabilizer and cause it to fail during flight.
❑Mix a generous amount of 30 minute epoxy and carefully apply a thin layer to the gluing surfaces of the stabilizer
assembly and to the gluing surfaces of the stabilizer mounting platform.
❑Set the stabilizer assembly back into place and realign it, double-checking all of your measurements once more before
the epoxy sets up. Remember to remove any excess epoxy before it sets up, using a paper towel and rubbing alcohol.
❑After the epoxy has fully cured, remove the masking tape and look closely at the glue joint. If there are any gaps
between the stabilizer assembly and the fuselage sides, fill them using 30 minute epoxy for added strength. Again, before
the epoxy sets up, remove any excess, using a paper towel and rubbing alcohol.
STEP 6: DOUBLE-CHECKING THE STABILIZER ASSEMBLY GLUE JOINT
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦If the stabilizer assembly is out of alignment, remove it and use 220 grit sandpaper with a sanding
block to sand down the higher side of the stabilizer mounting platform, then reinstall the stabilizer assembly and check
the alignment once more. Repeat this procedure until you are satisfied with the alignment.

SECTION 7: TOP WING INSTALLATION
STEP 1: INSTALLING THE STRUT MOUNTING PLATES
❑Remove the two ailerons and four C/A style hinges from the
top wing and set them aside for now.
❑Turn the wing upside down and carefully install the four
prebent aluminum strut mounting plates to the bottom of the
wing, using eight M3 x 12mm wood screws and eight M3 flat
washers. Holes have been predrilled in the wing to install the
wood screws. This ensures the proper location of the plates.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦

tighten them down yet. Leave the cabane struts slightly loose so that you are able to make adjustments to the assembly
when you install the top wing. This will make it much easier for you to line up the top wing properly. Note that blind nuts
have been preinstalled in the fuselage sides to mount the cabane struts to the fuselage, too.
❑Mount one short cabane strut (5-5/8" long) to the forward
hole in the left side of the fuselage and one longer cabane strut
(6-3/4" long) to the rear hole in the left side of the fuselage,
using two M3 x 10mm machine screws and two M3 flat washers.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦Note that there are right- and left-side
cabane struts. The struts also have a top and a bottom. On
the bottom of the struts, the distance between the end of the
strut and where the strut is bent is longer than on the top.

❑Repeat the previous procedures to mount the remaining two 5-5/8" long and 6-3/4" long cabane struts to the other side
of the fuselage, using two M3 x 10mm machine screws and two M3 flat washers.
❑Carefully test-fit and install one 7-5/8" long cabane strut to
the forward and rear cabane struts on one side of the fuselage,
using two M3 x 10mm machine screws, four M3 flat washers
and two M3 hex nuts.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦Note that there are right- and left-side struts
and the strut is prebent to fit properly only one way.
☞The cabane strut is mounted onto the outside surface of
the two other cabane struts, as shown.
❑Repeat the previous procedure to mount the remaining 7-5/8" long cabane strut to the remaining two cabane struts on
the other side of the fuselage, using two M3 x 10mm machine screws, four M3 flat washers and two M3 hex nuts.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦Notice than when the forward and rear cabane struts are joined together with the cabane support strut
that the forward cabane struts are basically straight up and down and the rear cabane struts are angled forward. This is
normal and by design.
STEP 3: INSTALLING THE OUTER STRUTS
❑Install two outer struts and one outer support strut to the
plywood mounting tabs on one side of only the bottom wing,
using four M3 x 10mm socket-cap screws and four M3 flat washers.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦The strut that's mounted to the forward
mounting tab should be mounted directly to the outside
surface of the mounting tab. The strut that's mounted to the
rear mounting tab should be mounted on the outside surface
of the mounting tab, then secured into place by positioning
the preinstalled blind nut in one end of the outer support
strut onto the inside surface of the mounting tab, as shown.
❑Repeat the previous procedures to mount the remaining two outer struts and the one remaining outer support strut to
the plywood mounting tabs on the other side of the bottom wing. Make sure that the outer struts are mounted to the outside
surface of the mounting tabs and that the outer support strut is mounted to the inside surface of the rear strut mounting tab.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦When lined up properly, as shown in the photo above, the outer struts will be naturally angled forward.
This is normal and by design.
✦✦
✦✦
✦INFORMATION ABOUT THE OUTER STRUTS✦✦
✦✦
✦
The full-size SE5a aircraft features only two vertical outer struts to support each end of both wings. In addition, though,
the full-size SE5a features a multitude of flying wires that support the wings and keep them from twisting and getting out
of alignment during flight. To keep our stand-off scale model of the SE5a easier to assemble, disassemble and
transport, we have opted not to use these cumbersome flying wires, but instead to use a single outer support strut to
keep the wings from twisting and getting out of alignment. While not exactly scale, this makes it much easier to disas-
semble and transport your airplane to and from the flying field.
❑Using a modeling knife, cut away and remove the covering material from over both sides of each predrilled hole in each
end of the four outer struts (W43) and the two outer support struts (W42). Cut away and remove the covering material from
the strut mounting tabs on the top and bottom wing, too.

STEP 4: ALIGNING AND MOUNTING THE TOP WING
❑Attach your incidence meter to one side of the bottom wing
and check the incidence. Adjust the height of the front or back
of the stand and/or fuselage so that the incidence meter reads
zero degrees (0º).
☞It may be necessary to use a block of wood or a book to
prop up one end of your airplane stand. If you need to prop it
up, make sure it is secure. It's important that the airplane stand
cannot move.
❑With the bottom wing installed onto the fuselage, set the fuselage in your airplane stand and secure it firmly to the stand,
using a couple of large rubber bands or several small weights.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦It's important that the fuselage be secured firmly and cannot move during the next few procedures.
❑Carefully set the top wing onto the cabane struts and the
outer struts, and temporarily secure it into place. Secure the
top wing to the cabane struts, using four M3 x 10mm machine
screws, eight M3 flat washers and four M3 lock nuts, then
secure the outer struts to the top wing, using four M3 x 10
socket-cap screws and four M3 flat washers.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦The cabane struts should be mounted on
the outside surface of the strut mounting tabs and the outer
struts and support struts should be mounted in the same
manner that they were mounted to the bottom wing.
Airplane shown upside down for photo clarity only
❑With the top wing held temporarily in place, attach your
incidence meter to one side of the top wing.
❑Carefully adjust the cabane struts and the outer struts until
the incidence meter reads minus one degree (-1º). When
satisfied with the alignment, completely tighten all of the
mounting screws and hex nuts to lock the top wing, cabane
strut assembly and the outer struts into place.
❑Remove the incidence meter from the wing, then remove the fuselage from your airplane stand.
❑Look carefully from the top of the airplane at both the top and the bottom wings. The leading edges and trailing edges
of the top and bottom wings should be parallel to each other. Now, look carefully at the airplane from the front. The top
wing should be parallel to the bottom wing and the top wing should be parallel to the horizontal stabilizer, too.
❑Look carefully from the end of the top and bottom wings and check for any twisting or warping in either wing. Neither
wing should be twisted or warped.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦If you see any irregularities in the alignment of the wings, you will need to loosen and readjust the
cabane struts and the outer struts, until you are satisfied with the alignment. Take your time. It's important.

✦INFORMATION ABOUT WING ASSEMBLY BEFORE FLIGHT✦✦
✦✦
✦
After you're done with the complete assembly of the airplane, but before you fly the airplane for the first time, we strongly
suggest that you apply Blue Threadlocker to the machine screws and nuts that secure the cabane strut assembly
together. This includes the four machine screws in the fuselage sides and the four machine screws and hex nuts that
secure the cabane strut supports to the front and rear cabane struts. It is not necessary to use Blue Threadlocker on the
four nylon-insert lock nuts or the four socket-cap screws that hold the outer struts in place.
We strongly suggest removing one by one the eight M3 x 12mm wood screws that hold the aluminum strut mounting
plates to the top wing and carefully reinstalling the screws, using a very thin layer of 5 minute epoxy, to secure them into
the wing. This will ensure that the wood screws will never come loose during flight.

SECTION 8: CONTROL SURFACE HINGING
STEP 1: HINGING THE AILERONS
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦The top and bottom ailerons are different, so make sure that you hinge them correctly. You can tell
which two ailerons are hinged to the bottom wing by looking carefully at the bottom of each aileron. The bottom wing
ailerons have a preinstalled balsa support block glued behind the leading edge that is used to mount the aileron control
horn to. You should be able to see this block pretty easily underneath the covering material.
❑Push two T-pins through the center of two C/A style aileron
hinges, as shown.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦The T-pins will keep the hinges centered
while you are hinging the aileron.
☞Each aileron is hinged using two C/A style hinges.
❑Working with one aileron for now, slide one hinge into each
hinge slot, making sure that you push each hinge in up to the
T-pins. Don't glue the hinges into place yet.
❑Push the aileron and its hinges into the hinge slots in the
trailing edge of the wing. The aileron should be pushed firmly
up against the trailing edge, so that there is a minimal hinge
gap (no more than 1/32"), and the tip of the aileron should be
even with the tip of the wing. The inboard edge of the aileron
should not rub against the edge of the wing, either.

☛☛
☛☛
☛

❑Remove the T-pins from the hinges, and while holding the
aileron tight against the wing, pivot the aileron down about
45º and apply 5-6 drops of thin C/A to the exposed area of
each hinge. Turn the wing over and repeat for the other side of
the hinges.
☞Remove any C/A that may run down the hinge line, using
C/A Debonder.
❑Allow the C/A to dry for about 15 minutes, then pivot the
aileron up and down several times to free up the hinges.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦After the C/A has fully cured, gently grasp the aileron and wing and pull on the aileron like you are
trying to pull out the hinges. The hinges should hold securely. If one or more hinge(s) feels loose, apply more C/A to the
hinge(s) and allow it to completely cure.
❑Repeat the previous procedures to hinge the remaining three ailerons to the top and bottom wings, making sure to
check the integrity of the hinges after the C/A fully cures.
STEP 2: HINGING THE ELEVATOR & THE RUDDER
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦The elevator must be hinged before the
rudder. If you hinge the rudder first, it will be impossible to
hinge the elevator.
❑Hinge the elevator and the rudder, using the same techniques
as you used to hinge the ailerons. The elevator is hinged
using four hinges and the rudder is hinged using three hinges.
You must cut away and remove the covering material from over
the precut notch in the leading edge of the rudder before hinging
it into place. The notch is located 1-7/8" up from the bottom of
the rudder, at the leading edge.

STEP 1: INSTALLING THE ENGINE MOUNTING BEAMS
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦When installed, the engine mounting beams are spaced to fit the Magnum XLS .40 - .52 size two-
stroke engines and the Magnum XL .52 - .61 size four-stroke engines. If the width of the engine you choose is not the
same, you will need to modify the spacing of the beams. This can be done by removing the blind nuts and gluing pieces
of hardwood dowel into the existing holes. You can then redrill the holes to fit your engine's width and reinstall the blind nuts.
❑Install the two engine mounting beams onto the firewall,
using four M3 x 18mm socket-cap screws and four M3 flat
washers. Tighten the screws firmly to hold the beams securely
in place.
☞Blind nuts have been preinstalled into the back of the
firewall to thread the screws into. We suggest applying Blue
Threadlocker to the screws to secure them into place.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦The engine is mounted upright.
STEP 2: ALIGNING AND INSTALLING THE ENGINE
❑Using a pencil, carefully mark the locations of the engine mounting holes onto the mounting beams.
❑Remove the engine and drill 5/64" diameter pilot holes through the engine mounting beams at the marks you drew.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦Be careful that you drill the holes straight down and not at an angle.
❑Carefully enlarge the 5/64" diameter pilot holes, using a 1/8" diameter drill bit.
❑Set the engine onto the engine mounting beams.
❑Using a ruler, measure the distance from the firewall to the
back of the propeller hub. Adjust the depth of the engine so
that the measurement is 4-3/4".
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦It's important that the back of the propeller
hub be 4-3/4" from the firewall so that the cowling will
line up properly when it's installed later. Do measure to the
front of the propeller hub.
❑Install the engine using four M3 x 25mm socket-cap screws,
eight M3 flat washers and four M3 lock nuts.
☞Tighten the screws and nuts firmly to hold the engine
securely into place.
❑Slide the propeller onto your engine and secure it into place, using your engine's propeller washer and nut.
Firewall has right thrust
built-in. This is normal
and by design. This is
the reason the engine
mounting beams are
mounted off-center.

SECTION 10: FUEL TANK ASSEMBLY & INSTALLATION
STEP 1: ASSEMBLING THE RUBBER STOPPER
❑Using 220 grit sandpaper, carefully smooth and deburr each end of the two aluminum tubes. This will prevent the fuel
tubing from being accidentally cut when it is installed later.
❑Carefully bend the longer of the two aluminum tubes up at a 45º angle, being careful not to "kink" the tubing as you
bend it.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦When the stopper assembly is installed in the fuel tank, the top of the vent tube (the tube you just bent)
should rest just below the top of the tank. The top of the fuel tank is a farther distance from the center of the fuel tank
opening than the bottom of the fuel tank.
❑Push the two aluminum tubes through the rubber stopper.
Slide the large diameter metal plate over the tubes at the front
of the stopper and slide the small diameter metal plate over
the tubes at the rear of the stopper.
❑Using a ruler, measure the distance that the two aluminum
tubes protrude from the front of the stopper assembly. This
distance should be 3/8". If it is not, adjust the tubes by pushing
them forward or backward until you are satisfied with the
alignment.
❑Push the M3 x 20mm machine screw through the stopper assembly, from the front, and partially thread it into the small
diameter metal backplate.
❑Secure one end of the silicon fuel tubing onto the end of the
fuel pick-up "clunk."
❑Slide the silicon fuel tubing, with the fuel pick-up attached,
onto the end of the aluminum fuel pick-up tube (straight tube).
While holding the aluminum tube in place, adjust the length of
the silicon tubing until the fuel pick-up is 3-3/8" back from the
rear of the stopper assembly.

STEP 2: INSTALLING THE RUBBER STOPPER ASSEMBLY
❑Carefully push the metal neck-reinforcement ring over the
neck of the molded fuel tank opening.
❑Carefully push the rubber stopper assembly into the fuel
tank opening and rotate the stopper assembly until the aluminum
vent tube rests just below the top of the tank.
If you have trouble seeing the vent tube, hold
the fuel tank assembly up to a bright light. This will illuminate
the inside of the tank.
PRO TIP
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦The top of the fuel tank is a farther distance from the center of the fuel tank opening than the bottom
of the fuel tank.
❑When satisfied with the alignment, tighten the machine screw until the rubber stopper expands and seals the fuel
tank opening.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦Don't overtighten the machine screw or you might strip the threads in the small metal plate.
❑With the rubber stopper assembly installed, double-check to make sure that the fuel pick-up can move freely inside the
fuel tank. Ideally, the fuel pick-up should be about 1/4" in front of the back of the fuel tank.
STEP 3: INSTALLING THE FUEL TANK
❑Cut two pieces of silicon fuel tubing to a length of 8" and install them to the aluminum tubes at the front of the tank.
Mark the ends of the silicon tubing "vent" and "pick-up" so you don't confuse them when it comes time to
connect them to the engine later on.
❑Feed the ends of the fuel tubing through the predrilled hole in the firewall and slide the fuel tank into position, making
sure that the stopper assembly lines up with, and is pushed into, the predrilled hole in the firewall.
❑To align the fuel tank properly, the fuel tank should be pushed forward as far as possible and the bottom of the fuel tank
should rest on the edges of the cutout in the forward bulkhead.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦When you slide the fuel tank into position, make sure that the top of the fuel tank is toward the top of
the fuselage. The top of the fuel tank is a farther distance from the center of the fuel tank opening than the bottom of the
fuel tank.
PRO TIP
❑To secure the fuel tank assembly into place, cut and install
several pieces of foam rubber between the top of the fuel tank
and the top of the cutout in the forward bulkhead.
☞Make sure that the foam rubber will not interfere with
the installation of your engine's throttle pushrod wire, which
will be done in the next section.

SECTION 11: THROTTLE CONTROL SYSTEM INSTALLATION
STEP 1: INSTALLING THE SERVO TRAY
❑Place the servo tray onto the balsa support rails, making
sure that the notch in the sides of the servo tray fit around the
plywood block on the fuselage sides.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦Orientate the servo tray so that the servo
cutout in the front of the servo tray is toward the right side of
the fuselage, as shown. This will ensure that the throttle
servo will line up with the throttle pushrod wire when they're
installed later.
❑When satisfied with the fit, glue the servo tray into place, using a generous amount of 5 minute epoxy. Remove any
excess epoxy, using a paper towel and rubbing alcohol, and allow the epoxy to completely set up before proceeding.
STEP 2: INSTALLING THE THROTTLE SERVO
❑Install the rubber grommets and brass collets onto your throttle servo, making sure to install the collets with the flanges
toward the bottom of the servo.
❑Install the throttle servo into the cutout in the front of the
plywood servo tray, making sure to first drill 1/16" diameter
pilot holes for the mounting screws.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦The servo output shaft should be toward
the right side of the fuselage, as shown.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦Don't overtighten the servo mounting screws. If the rubber grommets are completely crushed down,
the vibration dampening effect of the grommets will be reduced.
